my mailfilter.properties

SIEVE_LOGIN_TYPE=global
SIEVE_CREDSRC=imapLogin
SIEVE_SERVER=localhost
SIEVE_PORT=2000
SCRIPT_NAME=Open-Xchange

I've installed dovecot 1.1.7 with Sieve plugin v1.1.5 and ox 6.6.

relevant parts of my dovecot.conf

protocol lda {
        postmaster_address = postmaster@foo.com
        sendmail_path = /usr/sbin/sendmail

        mail_plugin_dir = /usr/local/lib/dovecot/lda
        mail_plugins = quota expire cmusieve
}
plugin {
        sieve = /data/fs/mail/sieve-scripts/%u.sieve
}

IMAP is ok, but if I want to create a filter the same error occcurs.
If I start dovecot there is no hint, that the siveplugin is loaded, only the other plugins are indicated.

Can someone help me?
I found no helpful entries in this forum and I also found nothing with google.
Can it be, that I understand something wrong with the plugin and the ox-sieve-server?

Thanks,

cornfelt

Hi,

i've a Dovecot 1.1.6 working properly with SIEVE against OX6, so there is no problem with it. Are you sure the SIEVE Service is installed properly? (telnet localhost 2000 should print some output).

Greetings

Hi Martin,

at first, thanks for the response.
sieve seems to be installed following files are available:

/usr/local/libexec/dovecot/sieved
/usr/local/libexec/dovecot/sievec
/usr/local/lib/dovecot/lda/lib90_cmusieve_plugin.a
/usr/local/lib/dovecot/lda/lib90_cmusieve_plugin.so
/usr/local/lib/dovecot/lda/lib90_cmusieve_plugin.la

but telnet says "connection refused".
Well, there is no sieve server running. There must be something wrong in my dovecot-config. If I (re)starts dovecote no errors occur at stdout or in the log files.
I've tried to start sieved manuelly, but it seemse to be no daemon. It asks for a script (I think a sieve-filter-script??).
Can you give me more hints or tips?

Thanks ,

cornfelt

Hi,

i installed Dovecot on Debian and had to compile it myself because the SIEVE plugin is only one part of the implementation. The ManageSieve module also needs to compiled into Dovecot and is the management module which allows access via port 2000.

http://wiki.dovecot.org/LDA/Sieve

http://wiki.dovecot.org/ManageSieve

The compile process itself was pretty straight-forward but requires some dependencies to build all the stuff.

Hope that helps

Hi,

thanks for the hints.
I didn't know, that I have to install ManageSieve too.

Now, everything works fine.

sieve filter don't work

I was to fast.

The filters don't working.
I create 2 filters to move some mails in another folder. I created both with the gui and both appear in the user-sieve-file.
But if I get an email it arrives in the inbox.

Additionally infos
- I use postfix, maildrop and spamassassin too

If I get an email in ox and look at the dovecotinfo.log (with mail_debug=yes) there is no entry with sieve or managesieve.
If I set a filter managesieve appears in this logfile.

Why don't work the filter.

Hi,

could it be that LDA is not used at all on your setup? Just a guess because you mentioned maildrop...

Greetings

[cornfelt]

our email-acocunts are only mentioned in the database. there are no unix-user-accounts.
what have I to do and to note that lda is used (a little howto)?
?????

or

is there another way to use sieve-filter, without lda?

[Martin Heiland]

The sieve filter will only be used if the E-Mail is delivered via LDA, otherwise it won't do anything (my guess).

Take a look:

http://wiki.dovecot.org/LDA/Postfix

[cornfelt]

is there a chance to use maildrop as mailfilter together with ox?

[cornfelt]

I've decided against maildrop and for dovecot as virtual transporter.
And now the sieve filter works fine.

Thank you Martin for your help.
